Coil Binders

Coil binders are used for spiral binding various documents or files in most of the offices and workplaces. Coil binders can be mechanical requiring use of manual power or electric powered automatic coil binders. Although, electric coil binders are replacing manual ones at a rapid pace. Coil binders can punch up to 20 -25 sheets at once and the binding capacity can be in the range of 400-500 sheets. Most support plastic or metal spirals which are used for binding of up to 20mm - 50mm diameter. Coil binders normally support A4 and A5 size papers as these are the most commonly used for spiral binding. Although, there are certainly coil binders supporting other paper sizes in the market.
